More than 30,000 new cases of oral cancer are reported each year, with an increasingly high number found in nonsmoking women. Many of the oral squamous cell carcinomas found in nonsmokers occur at different sites than those typically detected in smokers. To help determine the reason for this difference, a team of researchers, led by Brendan J. Perry, BSC, MBBS, of the Princess Alexandra Hospital in Brisbane, Australia, sought to examine the relationship between the location of oral cancer lesions in smokers and nonsmokers. The team hypothesized that oral cancer in nonsmokers may occur more frequently at the site of chronic trauma, making recurring oral injury a potential carcinogen in otherwise healthy individuals. Study results were published in the paper “Sites of Origin of Oral Cavity Cancer in Nonsmokers vs Smokers: Possible Evidence of Dental Trauma Carcinogenesis and Its Importance Compared With Human Papillomavirus” in November by the Journal of the American Medical Association Otolaryngology—Head and Neck Surgery.
